OFFALY is one of the cleanest counties in the country when it comes to Co2 emissions for private cars according to figures released last week.
The figures, released by Cartel, show that Offaly comes 23rd of the 29 areas surveyed recording average Co2 of just 133.4685 per km, well below the national average.
The results show that Dublin vehicles are emitting considerably more Co2 on average than any other county in Ireland. Leinster is the dirtiest province.
At the other end of the scale the cleanest county in Ireland for private vehicle use is Leitrim which records average Co2 of just 132.3521 per km.
Other notable counties include Cork which is listed in 15th position on the chart despite the fact it has the second highest number of vehicles per county.
The cleanest province is Connaught which occupies three of the cleanest five positions on the chart.
The dirtiest province is Leinster; largely due to the Dublin and Meath results.
